so i've got some neon lights, leds, and my radar dectector that i want to hardwire into my fuse box. i bought a splitter type thing that hooks into my fuse box and splits it into 6 wire terminals. what would be a good fuse to wire this into. preferably one that is only on when the car is on. some sort of accesory fuse maybe?
I would just hard wire it to the radio fuse. That's what I have always hard wired things to.
Use a relay. Run a wire from something that is switched in the box to the relay and then one wire to constant 12+. That way, you're not drawing all the power through your fuse box and poping fuses all the time.
